Over time, the Watch Tower Society has completely changed many of its beliefs. For example, until recently, the WTS said that the emblems of the Memorial represented the Church, the 144,000, that the emblems did not symbolize Jesus.
At times, the WTS changes the name of a belief while it continues the teaching, For example, the WTS used to say that Jesus and the 144,000 together were the "The Christ". Today, the WTS denies this teaching but the name "Anointed" means "Christ".
